This was reported a couple of days ago: ​U.S. President Donald Trump agreed "in principle" to scrap a warhead weight limit on South Korea's missiles in the wake of North Korea's sixth nuclear test, the White House said on Monday. During a call with South Korean President Moon Jae-in, Trump also gave "conceptual approval" for South Korea to buy billions of dollars of weapons from the United States, the White House said in a statement. Separately, South Korea's presidential office said the two leaders had agreed to scrap the weight limit and to apply the strongest sanctions and pressure on North Korea through the United Nations. Remember during President Trump's campaign and after winning the Presidency, that President Trump on multiple occasions has expressed that US allies need to pay for their American protection. This may just be what Trump is doing with the North Korean crisis, in that Trump is using it to finally force allies to pay for their American protection. Concerning South Korea itself...President Trump has expressed his willingness to cancel a US/South Korea trade program with the South. ​ With this crisis in North Korea, if allies like Japan and South Korea don't pay for their protection from America that has basically been going on for decades...Trump could eventually pull all US protection from these nations during this crisis in North Korea. Trump's a businessman and you need to remember that, and Trump may be putting US protection of South Korea and Japan in the cross hairs if they don't pay up.for US protection.
